European standard weld neck flange with tapered bore. EN 1092-1 Type 11 (equivalent DIN 2632-2635). DN15-DN1000, PN2.5-PN160.
The EN 1092-1 Type 11 Weld Neck Flange features a long tapered hub that transitions smoothly into the pipe bore, providing the highest mechanical strength and fatigue resistance among all flange types. The hub is butt-welded to the pipe, making it ideal for critical service applications.
JIAJI FORGING manufactures Type 11 Weld Neck flanges in austenitic stainless steel, duplex & super duplex stainless steel (EN 1.4462, 1.4410), and nickel alloys (Inconel, Hastelloy, Monel) for the global market.
